Funnels, web apps, micro-tools, features, video sales letters, task systems. Each one hands your AI a real blueprint to build from instead of a blank prompt — so you start from a plan, not a guess.

Mark up a screenshot, publish the list as a private URL, and your agent works through it one task at a time. Screenshot in, finished task out — no project manager in the middle.

Stop losing days to features you have built a hundred times. Grab a link, hand it to your agent, and it builds the feature into the app you already have — your stack, your components, your design system.

A one-line idea turns into the brief your AI coder actually needs: research, PRD, design direction, mockups, and a copy-paste build prompt. Or start from a plan somebody already finished.

Pick a funnel type and hand one link to the AI builder that already knows your app. It gets the pattern, the edge cases, and the build checklist in a format it can actually use.

No account, no plan, nothing to buy. They run on your own machine, and the source is there to read. They are not part of the suite — they are just what came out of building it.
A local, always-on operator that owns your missions, queue, approvals and schedules, then hands the real work to Codex. It starts with your computer, keeps everything in ~/.nabu, and never opens a port to the internet.

Chat with agents that build real tools — compiled Go services, not prompts. Give them a job and they go and do it, hand work to each other, and keep your dashboards refreshing around the clock for zero tokens.
Workbench finds every project on your drive, runs the ones you trust, takes a real screenshot of each, and puts them all on one shelf. It is not lost. It was just unlabelled.

wynter — building this page
pasted-image_339ad867.png can you centere these in theri boxes so it looks nicers
Three typos, no punctuation, and a screenshot pasted in the middle of the sentence. The boxes got centred. That is the bar now — you have to know what you want, not how to phrase it.
Which is roughly the idea behind all of this: hand the model something specific, and let it do the typing.
Bring your own key
The apps are free. The AI inside them runs on your own OpenAI or Anthropic (Claude) account, so you get the full models at your provider's price with no markup from us.
Create your free Wynter.ai Account
One signup opens all six apps. No card, no plan, nothing to unlock.
Get an API key from your provider
OpenAI keys live at platform.openai.com/api-keys; Anthropic (Claude) keys at console.anthropic.com/settings/keys. Either one works.
Paste it into the app's AI keys settings
Each app has its own AI keys settings page. Your key is stored encrypted and shown masked, and it's only ever used for your own requests.
You pay OpenAI or Anthropic directly for what you use. Wynter never sees a charge, and neither do you from us.
Pricing
No plan, no tiers, no top-ups, no credit card. The only thing the AI features need is an API key you already own — and you pay your provider directly, at their cost.
